The handgrip accommodates a automatic focus adjusting mechanism, which effects automatic focus adjustment of an image focusing optical system for focusing an image of an object on an image pick-up plane by emitting measuring light from a light emitting section and measuring the distance of the object from a lens by detecting the measuring light reflected by the object in a light receiving section. Either the center of the measuring light emitted from the light emitting section or the center of the measuring light incident on the light receiving section coincides with the optical axis of an image pick-up optical system. | |
